Further, said drive unit comprises the solenoid valve of the cylinder that is arranged on the clamp body and control cylinder action, and the said part type seal that expands is arranged on the piston rod of cylinder solenoid valve and air-leakage detector electrical connection;

Further, the type seal is expanded for making volume become big inflatable type seal through inflation in said part;

Further, said inflatable type seal is an air bag;

Further, the type seal is expanded for to be processed and the bloated body adaptive with orifice shapes by rubber in said part, said bloated body can fill in the part aperture and with its interference fit;

Further, said clamp body is provided with and is used to fill inner cavity of component to shorten the filling material of inflationtime;

Further, said safety detector is the infrared ray safety detector that is provided with infra-red alarm.

Beneficial effect of the present invention: the type that expands in the part of the present invention sealing leak tester; The type seal that expands in the part is filled in the part aperture; Mode through inner tensioning seals; Be applicable to the aperture of different shape, eliminated the defective of the port closing difficulty that causes because of situation such as aperture complex contour and end face flatness are bad, very big raising part leak detection level; The safety detector that is provided with simultaneously can prevent that part from detecting under clamping situation not in place, can guarantee equipment operation safety, detects accurately and reliably; The assembling of part and the local type seal spare that expands is accomplished through air-leakage detector control automatically, very big raising detection efficiency.

Embodiment

Fig. 1 is the structural representation of the type sealing leak tester that expands in the part of the present invention; Fig. 2 is the zoomed-in view of P portion among Fig. 1; Fig. 3 is the expand structural representation of type seal obturator of the part of being processed by rubber; Fig. 4 is the synoptic diagram of inflatable type seal; Fig. 5 is the structural representation of inflatable type seal obturator.

As shown in the figure; The bloated type of present embodiment local interior seals leak tester; Comprise air-leakage detector 1, anchor clamps and safety detector 2, said anchor clamps comprise jig main body 3, be used to fill in expand type seal 4 and be arranged at and be used to drive the drive unit that the local type seal that expands moves on the clamp body of part that shutoff part aperture makes the aperture sealing; Said air-leakage detector 1 is electrically connected with drive unit; The action of air-leakage detector 1 accessory drive; Said safety detector 2 is electrically connected with air-leakage detector 1; Safety detector 2 is used to detect the assembled state of part and clamp body 3 and the local type seal 4 that expands, and with detection information input air-leakage detector 1.

The type that expands in the part of the present invention sealing leak tester; The type seal 4 that expands in the part is filled in the part aperture; Mode through inner tensioning seals; It is applicable to the aperture of different shape, has eliminated the defective of the port closing difficulty that causes because of situation such as aperture complex contour and end face flatness are bad, very big raising part leak detection level; The safety detector that is provided with simultaneously can prevent that part from detecting under clamping situation not in place, can guarantee equipment operation safety, detects accurately and reliably; The assembling of part and the local type seal spare that expands is accomplished through air-leakage detector control automatically, very big raising detection efficiency.

As the improvement to this embodiment, said drive unit comprises the solenoid valve 6 of the cylinder that is arranged on the clamp body 35 and control cylinder 5 actions, and the said part type seal 4 that expands is arranged on the piston rod of cylinder 5, and solenoid valve 6 is electrically connected with air-leakage detector 1.After air-leakage detector 1 is received the signal that part that safety detector 2 sends and clamp body 3 be seated; Air-leakage detector 1 sends control signal to solenoid valve 6; Make cylinder 5 promote the local interior type seal 4 that expands and get into the part mouths of pipe; The sealing of expanding in line up carries out, when air-leakage detector 1 receive expand part that safety detector 2 sends type seal 4 be seated signal with part after, air-leakage detector 1 begins leak detection.After leak detection finished, the hold down gag of air-leakage detector 1 control clamp body 3 unclamped, and control electromagnetic valve 6 makes the type seal 4 that expands in the cylinder 5 driving parts withdraw from the part mouth of pipe.The type that expands in the part of the present invention sealing leak tester leak detection process realizes robotization control, and the leak detection operating efficiency is high.
